在视口上重叠画布以捕获WPF中的鼠标事件 [英] Overlapping the Canvas on the viewport to catch mouse events in WPF

问题描述

我发现最近有关​​WPF 3D图表的文章非常有帮助. (http://www.codeproject.com/KB/WPF/WPFChart3D.aspx) 我正在寻求了解如何在我自己的WPF 3D应用程序中捕获鼠标按下事件.我尝试了宣告Canvas并捕获其鼠标事件的文章技术.但是，它对我不起作用.是否有人知道是否必须在XAML中声明viewPort才能使此技术起作用.目前，我的viewPort是用C#代码在XAML中用画布声明的.

I found a recent article on WPF 3D charts very helpful. (http://www.codeproject.com/KB/WPF/WPFChart3D.aspx)  I am seeking to understand how to catch mouse down events in my own WPF 3D App. I tried the article technique of declaring a Canvas and catching its mouse events. However it is not working for me. Does anyone know whether the viewPort has to be declared in XAML for this technique to work. Currently my viewPort is declared in C# code with the canvas in XAML.

感谢您抽出时间回答我的问题.

您能告诉我是否必须在XAML中声明viewPort才能使该技术起作用.目前，我的viewPort在C#代码中用XAML的画布声明.

Can you tell me whether the viewPort has to be declared in XAML for this technique to work. Currently my viewPort is declared in C# code with the canvas in XAML.

什么都不需要仅在XAML中声明，如果它存在，它就已经存在. XAML只是创建相同对象的另一种方法.

Nothing EVER needs to be declared only in XAML, if it exists, it exists.  XAML is just another way to create the same objects.
